Answer:
B. Convert mass percents to moles and then divide by the smallest mole value to get subscripts
Explanation:
The empirical formula is the smallest whole number ratio the elements in a compound can possess. According to this question, to derive the empirical formula of a compound from its percent composition of elements that make it up, the following steps are followed:
- First, since the elements are in percentage, one would assume the total mass of the compound is 100g and take each percentage as the mass of each element. For example, if a compound contains 16% oxygen, it means that 16g of oxygen is present.
- Next, we convert the mass of each element to moles by dividing the mass value by the molar mass of each element. For example, 16g of oxygen will be 16g/16g/mol = 1mol
- Next, we divide each mole value by the smallest mole value to get the subscript of each element that will be used in the empirical formula.
Answer:
its a
Explanation:
The Great Lakes region has both biotic and abiotic components. Abiotic components include water, temperature, rainfall, and geological features. Biotic components include all of the animal and plant species in the area.
It's hydrogen peroxide plus carbon plus hi Hydrogen plus oxygen plus carbon hydroxide iron
The molecule of mixture cannot be seen hence, it will be considered as homogeneous mixture.
<h3>
What is molecule?</h3>
A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.
<h3>
What is homogeneous mixture?</h3>
Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.
When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.
Therefore mixture can be considered as molecule and homogeneous mixture.
